LOUIS BASTET, SOUTLEIORANGE, NEW JERSEY, ASSIGNOR OF ONE-HALF TO IVILLIS A. BARNES, OF NEW YORK, N. Y.

ELASTIC PAPER OR FELTING FOR CARPET-LlNlNG.

SPECIFICATION forming part of Letters Patent No. 346,799, dated August 3, 1886.

Application filed October 15, .1885. Serial No. 1l9,979. (Specimens) T0 at whom it may concern:

Be it kown that I, LoUIs BASTET, a citizen of the United States, residing at South Orange, in the county of Essex and State of New Jersey, have invented new and useful improvements' in a combination of substances for the manufacture of an improved elasticv paper or felting for carpeting-lining, of which the following is a specification.

This invention relates to materials used for carpet-lining, sheathing, 850.; and it consists in the combination'of certain waste products, hereinafter mentioned, to produce a fabric or felt of superior qualities for that purpose. The material which composes the carpet-lining is corn-cob in combination with raw paper-stocks, known in the trade as colors or satinets, or the waste of carpet and woolen mills, known as shoddy. I may, however, use as a paper-stock the fiber of the typhalatifol ta after treatment by chemical process, or

with sawdust or any equivalent material mixed with it to give strength and durability to this fiber, any common paper-stock may be used with the corn-cob.

In the preparation of the corn-cob to be used in the manufacture of my elastic carpet-lining, it is carefully selected and freed from any attaching kernels of corn, corn-silk, or hulls of the corn. The cob is then ground in a burrstone grinding-mill, or any other suitable mill,

to about the fineness of wheat-bran, care being taken not to reduce it too fine for elasticity. It is then passed through sieves of the proper size, by which the imperfectly-ground portions of the cob and other useless substances are removed. The ground corn-cob is then ready for use in the manufacture of my elastic carpet-lining.

In the manufacture of my elastic carpet-lining from the materials above specified I grind the raw paper-stock in a grinding or triturating machine,'in a way similar to that in which paper-stock is now prepared, until the same is brought to a degree of fineness of pulverization requisite for its manufacture into paper, and just after the grinding process is complete I add the ground corn-cob, but do not pulp it.

I prefer to use from twenty-five to forty per cent. of the ground corn-cob in the manufacture of my elastic carpet-lining, though I do not limit myself to this proportion. Thetypha- Zatifoh'a is added in the proportion of five to ten per cent. but I do not limit myself to this proportion.

I mayomit the use of any one of the articles of paper-stock above specified, substituting a larger proportion of some of the other materials specified or supplying some equivalent material.

The advantages of my invention are adding to the useful arts a new product in the manufacture of carpet-lining of a very elastic nature, whereby the wear or use of carpets may be very largely increased, and it also provides an elastic carpet-lining better and cheaper than any hitherto used. It is also an excellent material for packing glassware. The superiority of the fabric thus partly composed of corn-cob is due to the fact that while the cob is equally assoft and elastic as cork, which up to this time has been considered the best known substance for these qualities, the cob is spongy and will absorb water when mixed with the pulp, and thus mix uniformly with the restof the pulp, while cork, which resists the water, tends always to the surface and fails of uniform mixture.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

As a new article of manufacture, a felt or fabric composed of raw paper-stock, as above specified, in combination with ground corncobs, mixed with the pulp subsequently to the grinding of it, substantially as described, and for the purposes set forth. I

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

LOUIS BASTET.
